Abstract

A rotor (10) for an electric machine (40) includes a first elongated rotor segment (12) having a plurality of axially extending rotor poles (20) arranged in a circular array about a central axis (18) that extends longitudinally through the first rotor segment(12). A second axially extending rotor segment (14) engages and is fixed relative to the first rotor segment (12). The second rotor segment (14) has a plurality of axially extending rotor poles (38) arranged in a circular array about the central axis (18). The poles (38) of the second rotor segment (14) are rotated in a first direction about the central axis relative to the poles (20) of the first rotor segment (12). Preferably the rotor (10) also includes a third axially extending rotor segment (16) that engages and is fixed relative to at least one of the first and second rotor segments (12, 14). The third rotor segment (16) also has a plurality of axially extending rotor poles (44) arranged in a circular array about the central axis (18). The poles (44) of the third rotor segment (16) are rotated about the central axis (18) relative to the poles (20, 38) of each of the first and second rotor segments (12, 14).
